BACKGROUND Field

The present disclosure relates generally to intelligent systems that map optical fiber communication paths of one port density to optical fiber communication paths of a different port density while providing human perceivable indications to represent attached devices port status, to provide guidance for fiber moves, adds or changes, or for other end user intentions. Other intelligent functions of the system may include an ability to detect cable presence, logging of moves, adds and changes such as counters for cable insertions and extractions, and to identify and log cable characteristics such as color, length, ID, fiber type and such.

SUMMARY

The Intelligent Fiber Port Management System according to the present disclosure maps optical fiber communication paths of one density to optical fiber communication paths of a different density, for either breakout or aggregation functionality. For example, devices with one or more Quad Small Form-factor Pluggable (QSFP+) multi-fiber transceivers that interface with multi-fiber connectors can be mapped to devices with a plurality of small form factor (SFF) transceivers that interface with single fiber optic connectors. Examples of multi-fiber connectors may include but are not limited to Multi-fiber Push On (“MPO”) connectors, and examples of single fiber optic connectors may include but are not limited to Lucent Connectors (“LC”).

In an example where 20 QSFP+ MPO multi-fiber connections are to be mapped to LC single duplex fiber connections, each QSFP+ transceiver has 4 transmit (Tx) and 4 receive (Rx) fiber paths housed inside a 12 fiber MPO connector that are accessible from, for example, a rear panel of the Intelligent Fiber Port Management System. It should be noted that in this example, the remaining 4 fibers are inactive. The Fiber Port Management System internally provides the required breakout connectivity from the multi-fiber connections to the single fiber connectors. The result in this example is that 20 MPO connectors on a rear panel of the Fiber Port Management System can be mapped to 160 LC connectors on the front panel of the Fiber Port Management System with 80 paired ports.

In another example, a high density multifiber connection such as a 24 fiber MPO connector may break out the individual fibers to single fiber connectors such as bidirectional LC connections or into duplex LC connections supporting a Transmit fiber and a Receive fiber.

In another example, a high density multifiber connection such as a 24 fiber MPO connector may break out the individual fibers to multifiber connectors such as 12 fiber MPO connectors or 8 fiber MPO connectors which may connect to downstream devices with multifiber port connectors such as 12 fiber MPO connectors or other transceiver interfaces such as QSFP transceivers.

In addition, each multi-fiber connector on the Fiber Port Management System, e.g., each MPO connector, has one or more associated LEDs on either the front panel or the rear panel that is in close proximity to the relevant multi-fiber connector and that provides a visual indication programmable by an externally attached device, by an external Management System, or by any other criteria defined by an internal CPU. In the configuration shown, the one or more LEDs can be positioned above the multi-fiber connector. Each single fiber connector on the Fiber Port Management System, e.g., each quad LC connector, has one or more (e.g., two) LEDs on either the front panel or the rear panel that is in close proximity to the relevant single-fiber connector and that provides a visual indication programmable by an externally attached device, by an external Management System, or by any other criteria defined by the internal CPU. The one or more LEDs can have different colors to indicate defined conditions. The colors for the multi-fiber LEDs may be the same as the colors for the single-fiber LEDs or the colors for the multi-fiber LEDs may be different than the colors for the single-fiber LEDs.

DETAILED DESCRIPTION

The Fiber Port Management System 10 according to the present disclosure can be used to map optical fiber paths of one or more ports of, for example, a network device 50 having one fiber density to optical fiber paths having a different fiber density that can be used by one or more network appliances 60 or other network devices. For the purpose of the present disclosure, a network device can include network switches, patch panels, and other types of devices facilitating data center or network communications. The phrase network appliance can include, for example, data storage devices, servers and other computing devices that facilitate user interaction.

For example, and referring to FIG. 1, the Fiber Port Management System 10 according to the present disclosure can include a high port density side with one or more multi-fiber connectors and a low density side with one or more single or multi-fiber connectors. The high density side can be connected to one or more multi-fiber connectors of for example a network device 50 while the low density side can be connected to one or more network appliances 60. In this example, the network device is a network switch having one or more Quad Small Form-factor Pluggable (QSFP+) multi-fiber transceivers that interface with multi-fiber connectors, and the network appliances 60 are servers with small form factor (SFF) transceivers that interface with single fiber connectors. Using the Fiber Port Management System 10, the high density communication paths on the network device 50 can be mapped to a plurality of low density communication paths connected to a plurality of network appliances 60. Examples of multi-fiber connectors may include Multi-fiber Push On (“MPO”) connectors, MXC connectors, or other connectors capable of trunking more than one fiber in a single jacket. Examples of single fiber optic connectors may include Lucent (“LC”) connectors, SC connectors, FC/PC connectors, or other connector types that terminate single fiber cable. As noted, the Fiber Port Management System 10 includes one or more LEDs in close proximity to each multi-fiber connector and each single fiber connector that provide pre-defined visual indications. The Fiber Port Management System 10 includes a CPU that is in communication with the network device 50 via the bidirectional communication path 70. The CPU controls the operation of the LEDs in the Fiber Port Management System based any criteria defined by the attached network device 50.

As another example, and referring to FIG. 1, the CPU of the Fiber Port Management System 10 either queries or receives an unsolicited event from the attached network device or plurality of network devices 50 via path 70, representing the port status of the attached network device or plurality of network devices, then maps the status to a pre-defined LED color and or blink pattern.

As another example, and referring to FIG. 2, the Fiber Port Management System 10 includes a high port density side with one or more multi-fiber connectors and a low density side with one or more single fiber connectors. The high density side can be connected to one or more multi-fiber connectors of for example a network device 50 while the low density side can be connected to one or more network appliances 60. This example is similar to the embodiment of FIG. 1, except the CPU is in communication with an external management system via the bidirectional communication path 72. The external management system determines the behavior of the Fiber Port Management System's LEDs.

Referring to FIGS. 3-7, an exemplary housing for the Fiber Port Management System 10 of the present disclosure is shown. The housing 11 includes, for example, a base 12, side walls 13, a front panel 14, a rear panel 15 and a cover 16. The front and rear panels 14 and 15 of the housing 11 have a printed circuit board (PCB) secured thereto that has electronic components to drive the LEDs on the interior side and LEDs on the exterior side projecting through holes in the front panel 14 and the rear panel 15. Each LED is visible from an exterior of the housing 11 to permit visibility of the LED.

For the high density side of the Fiber Port Management System 10, the one or more multi-fiber connectors 20 can be connected to, for example, the front or rear panel of the housing 11, and for the low density side of the Fiber Port Management System 10, one or more single-fiber connectors 22 can be connected to, for example, the front or rear panel of the housing 11. An exemplary MPO to LC hydra cable 24, seen in FIG. 8, within the housing 11 splits or converts the fiber connections from the multi-fiber connectors to the single fiber connectors. For example, the hydra cable can split a 4×10 Gbps QSFP transceiver to four duplex SFP transceivers. The QSFP transceiver is connected to the rear chassis MPO connector by a straight 12 fiber MPO cable with MTP connectors. The multi-fiber cable can mate to the rear MPO connector in a key up position on the rear panel 15 of the housing 11 and key down position on the inside of the housing 11. The low density side of the hydra cables, e.g., LC #1-LC #8, is inserted into the LC connectors on, for example, the front panel 14 of the housing 11.

The Multi-fiber Termination Push-on (“MTP”) connectors, which are also called MPO connectors 20, and LC connectors 22 are mounted to openings in the PCB on the front and/or rear panels 14 and 15. Other embodiments may include higher density MPO connectors on the rear panel and lower density MPO connectors on the front panel. The LC connectors or adapters pass through openings on the PCB and mount to, for example, the front panel 14 of the housing 11, and may or may not be operatively connected to the PCB. As shown in FIGS. 6 and 7, the LC connectors 22 are arranged in this exemplary embodiment as 20 LC groups with two quad LC connectors per group. Each group has two LEDs 26 above and two LEDs 26 below the LC connectors 22. As seen in FIG. 5, the rear panel 15 of the housing 11 in the embodiment shown supports two AC input connectors, 20 MPO panel mount connectors 20, and a PCB mounted flush with the inside of the rear panel 15. The MPO connectors pass through openings on the PCB and mount to, for example, the rear panel 15 of the housing 11, and may or may not be operatively connected to the PCB attached to the rear panel 15. In other embodiments, the MPO connectors may be mounted to the PCB. The MPO connectors in this embodiment are configured as two rows with 10 MPO connectors 20 per row, as shown in FIG. 5. In addition, each MPO connector has a port status LED 26 above the MPO connector 20, as seen in FIG. 5.

In the exemplary configuration shown in FIG. 6, the front panel 14 of the housing 11 can include an RJ 45 jack Ethernet port, an RJ 45 jack Craft port, a USB connector port, 40 Quad LC panel mount connectors 22, port status LEDs 26, a power supply 1 status LED, a power supply 2 status LED and a CPU status LED. The front panel 14 may also include a recessed reset switch. The LEDs and reset switch are mounted to the front panel PCB which in turn is mounted flush with the inside of the front panel 14 of the housing 11. The port status LEDs 26 are associated with a particular port of the high density side or low density side of the fiber port aggregator 10.

Within the housing 11 is a CPU 80, seen in FIG. 4, and power supplies that provide power to the CPU. Referring to FIGS. 9 and 10, a wiring diagram of the CPU used to control the LEDs 26 is shown. As noted above, the LEDs 26 are mounted to PCBs attached to the front and rear panels of the housing 11. The CPU 80 has a ribbon cable 82 connected to the PCB 83 on the rear panel 15 of the housing 11. A ribbon cable 84 also connects between the PCB 85 attached to the front panel 14 of the housing 11 and the PCB 83 attached to the rear panel 15 of the housing 11. The AC power cable is connected between each AC power inlet to the line and neutral lugs on each power supply. The RJ 45 jack Ethernet port, RJ 45 jack Craft port, and USB connector port are connected to the CPU 80.
